MWITA-EBRO-2026-010 · Evidence A · P1
Referred online workers were more likely to accept an offer, submit work on time and continue than observably similar nonreferred workers, including on work performed under a different firm name without their referrers, indicating that referrals carried otherwise hidden information about worker quality and persistence.
What this does not establish
The result does not imply referrals causally improve a worker or guarantee diversity: much of the advantage is selection information, the tasks were low-wage online administrative work, and network access can exclude otherwise qualified candidates.
Counterevidence & uncertainty
Monitoring by referrers had no detectable performance effect, weakening a peer-pressure explanation and favoring information and team-complementarity mechanisms.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and realized behavioral or commercial outcomes.
